If anyone has input it would be appreciated.

Own a 2015 Passat TDI SEL

I have been getting my diesel at Cumberland Farms for the past few tanks. The last tank I got 400 miles from it which is unacceptable. I then filled up at Stop & Shop and got just over 550 miles. I drive the same commute about 70 % highway at 70mph or slower.

I just filled up again from Cumberland to make sure I am not loosing it and have just hit the 3/4 tank mark and am only at 90 miles.

Has anyone else had issues with Cumberland Diesel? Is there an issue with the car? Other than that the car runs fine.

I'm using C-F petrodiesel to winterize my bio. I'm at about a 2:1 (or B33) ratio until wather warms up to consistently above freezing. I haven't noticed any drop from usual, 3 season, B99, fuel use.

Petro foams quite a bit. A faster fill rate might shut off the pump with more foam, less fuel. So you fill up with a fast pump, put in less fuel making the prior fuel look more economical, then fill up at a slower pump that foams less, making the fill up prior to that look worse than reality.
